<p>A security feature bypass vulnerability exists in the PowerShellGet V2 module. An attacker who successfully exploited this vulnerability could bypass WDAC (Windows Defender Application Control) policy and execute arbitrary code on a policy locked-down machine.</p> <p>An attacker must have administrator privileges to create a configuration that includes installing PowerShellGet V2 module onto a machine from the PowerShell Gallery. The WDAC policy must be configured to allow the module to run. After this is done, PowerShell script can be injected and run fully trusted, allowing the attacker arbitrary code execution on the machine.</p> <p>The update addresses the vulnerability by changing how URLs are processed.</p>

SteelCentral Aternity Agent 11.0.0.120 on Windows mishandles IPC. It uses an executable running as a high privileged Windows service to perform administrative tasks and collect data from other processes. It distributes functionality among different processes and uses IPC (Inter-Process Communication) primitives to enable the processes to cooperate. Any user in the system is allowed to access the interprocess communication channel AternityAgentAssistantIpc, retrieve a serialized object and call object methods remotely. Among others, the methods allow any user to: (1) Create and/or overwrite arbitrary XML files across the system; (2) Create arbitrary directories across the system; and (3) Load arbitrary plugins (i.e., C# assemblies) from the "%PROGRAMFILES(X86)/Aternity Information Systems/Assistant/plugins” directory and execute code contained in them.
